I've tried different AT commands but am still getting the same result. Perhaps its a misconfiguration on my end. anyone have a wvdial conf or the correct init strings for this phone/service?

I *think* that the init strings are all the same, in that it's something to do with GSM dialing and not quite like a real modem (where different models might have different inits). Given that, I can supply my S60/Symbian values that might be relevant.

Notice that the last parameter in Init3 might be different depending on your plan with your carrier -- 'wap.voicestream.com' is suitable for the BlackBerry data plan on T-Mobile. Also, the Modem=/dev/rfcomm0 I think might be for when I use it with a USB cable, not a BT stack.
